BUBBLE-PIPE.

SPECIFICATION forming part Of Letters Patent N0. 432,415, dated July 15,1890.

Application filed February 12, 1890- Serial No. 340,167. (No model.)

To aZZ whmn it may concern.-

Be it known that I, ALONZO LEWIS, of Baltimore, in the State offMaryland, have invented a new and Improved Bubble-Pipe, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in pipes for blowing bubbles; andthe object of my invention is to provide a simple and inexpensive pipethat is especially adapted for use in blowing bubbles, and that willhold the water in such a manner that it will not be spilled.

To this end my invention consists in a hubble-pipe constructedsubstantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views. Figure 1 is a vertical section ofthe pipe embodying my invention, the same being filled with water readyfor use; Fig. 2, a vertical section of the same on the line 2 2 of Fig.1; Fig. 3, a horizontal section of the same on the line 3 3 of Fig. 2,showing the bubble-tube closed; and Fig. at, a horizontal section of thesame, showing the bubble-tube open.

The bowl A of the pipe is made of wood, metal, or of any suitablematerial, and is preferably cylindrical in form. It is provided with aremovable top or cover A and with a block B, which fits closely in thelower part thereof. The block B is provided with a horizontal bore 0,which extends entirely through the same, and in which are located theslideblocks D D the block D being shorter than the block D, with acentral vertical bore C extending through the same, and which intersectssaid bore C, and with a diagonal bore E, which extends from the verticalbore to the outer edge of the block, where it connects with thepipe-stemH. The block D is longitudinally movable in the bore 0, and the blocks Dand D are pressed together by the rubber bands a, the ends of which aresuitably fixed in the grooves cof the said blocks, as shown, by threadwound in the annular grooves b and over their ends. Fixed to the block Dis a rod d, which lies in the longitudinal grooves e of the blocks D Dand extends through the opening f in the side of the pipe-bowl A, sothat by pressing inwardly upon the end of the rod d the block D will bepushed outwardly and the blocks D and D forced apart. I do not confinemyself to the use of rubber bands to hold the blocks D and D together,as suitable springs or other elastic material might be substituted.

Extending through the vertical bore of the block 13, between the blocksD and D, is a rubber tube F, the upper end of which extends slightlyabove the block B, and into the water in the bowl A, and the lower endof which projects through the bottom A of the pipebowl, passing througha perforation in the same. The tube is provided upon one side with anopening (,which connects with the diagonal bore E, and thence with thepipestem H. It will be seen from the above description that the tube Fwill be normally closed by the pressure of the blocks D D upon it, andthat when the blocks are forced apart by the rod d the tube will beopened.

The bowl A of the pipe above the block B is filled with soapy water, andthe device is operated as follows: The operator. presses slightly on therod d, thus forcing the blocks D D apart and allowing a minute quantityof water to flow into the tube F. The pressure is then removed from therod and the blocks close the tube, as described. The operator then blowsthrough the pipe-stem H, and the air will pass through the stem, through the bore E of the block B, and through the opening g and tube F.There will be sufficient moisture in the tube F to form a bubble, whichwill be blown from the lower end of the tube, as shown in. Fig. 1.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A bubble-pipe comprising a reservoir, a rubberoutlet-pipe having a clamp or compress engaging it transversely to closeits bore by compression, means for releasing said clamp or compress, anda blow pipe or stem communicating with said rubber tube below its clampor compress, substantially as set forth.

2. A bubble-pipe consisting, essentially, of a bowl having a stemattached to the lower part thereof, a block fixed in the lower portionof the bowl, having avertical bore there= in, a rubber tube extendingthrough said vertical bore, a diagonal bore connecting said tube withthe pipe-stem, a horizontal bore extending through said block, and aclamp 01' compress for opening and closing the rubber tube,substantially as described.

3. In a bubble-pipe, thecombination, with a block located in the lowerpart of the bowl, provided with a diametrical bore, a central verticalbore, and a diagonal bore, and a tube located in said vertical bore, oftwo springaetuated blocks located in said diametrical bore at the sidesof said tube, and means for separating the blocks, substantially asdescribed.

4. The combination, in a bubble-pipe, with the pipe-bowl A,havinga stemH fixed in the lower part thereof, of the block B, having the rubbertube F extending vertically through the same, the bore E, extending fromthe pi pestem to a perforation g in said tube, and means, asspring-actuated blocks D l) and rod (Z, for opening and closing saidtube, substantially as described.

5. The combination, with the pipe F, arranged in the block B, as shown,and having means, as described, for blowing air and wator through thesame, of the blocks 1) I), having springs to hold the same against thetube F to close the tube, and having a rod (l, connecting the block Dwith the outside of the bowl, whereby the block may be moved and thetubeF opened, substantially as described.

ALONZO LEWIS.
